Eocene Gravity Flows in the Betic Cordillera, Spain
In the Betic-Rif Cordilleras, recent works have evidenced the existence of well-developed Eocene (Ypresian-Bartonian) carbonate platforms rich in Larger Benthic Foraminifera (LBF). Contrarily to other sectors of the western Tethys, like the Pyrenean domain in the North Iberian Margin, where these platforms started in the early Ypresian (Ilerdian), in the Betic-Rif chains, the recorded Eocene […]
Geosciences, Volume 15, Issue 3 (March 2025)
The march issue of the Geoscience journas has a cover story dealing with the newly published paper in that issue by Tosquella et al. (2025) of our group. In the Betic-Rif Cordilleras the Eocene platforms started in the Cuisian after a gap including the Ilerdian. An Eocene succession with gravity flows consisting of turbidites and […]
Paleocene-Eocene evolution of the Prebetics (South Spain) and comparison with other western Tethyan margins
Thirteen Paleocene-Eocene sections have been studied along the Prebetic Domain (South Iberian Margin) in the Alicante, Murcia, Granada, and Jaen Sectors. The sedimentary realms (mostly consisting in 15 shallow marine Lithofacies) and the tectono-sedimentary evolution were characterized. Three informal stratigraphic units were proposed and dated with planktic foraminifera, calcareous nannoplankton, and Larger Benthic Foraminifera (LBF): […]
The Eocene carbonate platforms of the westernmost Tethys: a review
According to the prevailing view in literature, two Eocene carbonate platform belts developed on northern and southern margins of the Tethys Ocean. However, Eocene platforms in the Malaguide −Ghomaride Units (Betic-Rifian Arc; Spain and Morocco, respectively) in intermediate position to the classic platform belts have been proposed in recent literature. A number of representative Ypresian […]
Spanish Geological Congress in Avila
A paper on geological cycles during the Eocene in the Prebetic (SE Spain) was presented at the XI Spanish Geological Congress held Ávila (Spain) from July 1 to 6, 2024. The picture show the poster and the participant José Enrique Tent-Manclús. Cite as: Tent-Manclús, J. E., Martín-Martín, M., Miclăuș, C., Tosquella, J., Serrano, F. y […]
Field trip in Morocco: Searching for the Nummulites
The Africa call… Well the third field work campaign the project. This time in the Middle Atlas of Morocco. The objetive was to find Nummulites as the ones in the Betic or in the Rif. The picture shows the members of the team. Picture taken by Soufian Maaté. Manuel Bullejos Lorenzo (Granada University) Rachid Hlila […]
Small scale RT cycles in Prebetic Lower-Middle Eocene (Alicante)
In the study of the Alicante External Prebetic Eocene platforms, ten sedimentary facies were defined in field based on lithology and fossil content observed, as follows: L1 – limestone (lmst.) with Alveolina; L2 – lmst. with small Nummulites (< 3 cm diameter); L3 – lmst. with big Nummulites (>3 cm diameter); L4 – algal lmst.; L5 – lmst. […]
New biostratigraphic data on the Paleocene-Eocene from the Prebetic
A biostratigraphic study of the Paleocene-Eocene of the stratigraphically continuous with the northern foreland (Iberian Meseta), Prebetic has been studied by using planktonic foraminifera, calcareous nannoplankton, and larger benthic foraminifera. Twelve sections have been studied along the chain: four sections in the Alicante Sector, four in the Murcia Sector, two in the Granada Sector, and two sections in the Jaén […]
